Abstract

BACKGROUND: Varicose veins of the lower limbs have a high prevalence worldwide. New treatment techniques have been developed with the objectives of improving patients' quality of life and reducing recovery times. OBJECTIVE: To evaluate patients with incompetent saphenous veins treated using conventional saphenectomy or radiofrequency ablation (RF), in terms of postoperative status. METHODS: From May 2012 to April 2013 146 varicose veins patients with saphenous insufficiency, 90 of whom were treated with conventional surgery (G1) and 56 with RF ablation (G2), were evaluated prospectively. RESULTS: In G1, 88.61% of patients complained of postoperative pain and needed to take analgesics, compared with 28.85% in G2 (p<0.05). Mean pain rating on an analog scale from 0 to 10 was 3.91±2.13 points for G1 and 1.76±3.01 points for G2 (p<0.05). Recovery periods ranged from 26.63±13.3 days to 18.26±19.37 days, for G1 and G2 respectively. Mean time taken to become totally asymptomatic was 66.78±60.9 days for G1 and 38.38±46.8 days for G2 (p<0.05). CONCLUSIONS: The RF treatment method caused less postoperative pain and resulted in earlier recovery, when compared to conventional saphenectomy.

Resumo

CONTEXTO: As varizes dos membros inferiores têm elevada prevalência mundial e as técnicas convencionais de tratamento têm seus resultados bem definidos há décadas. O advento de novas tecnologias nos obriga a avaliar os resultados e compará-los com métodos tradicionais. OBJETIVO: Avaliar o tratamento de pacientes com varizes dos membros inferiores e insuficiência de safenas por safenectomia convencional (SF) ou ablação por radiofrequência (RF), quanto aos sintomas pós-operatórios. MATERIAIS E MÉTODOS: Entre maio/2011 e abril/2013, foram avaliados prospectivamente 146 pacientes com varizes dos membros inferiores e insuficiência de safenas, sendo 90 por SF (G1) e 56 por RF (G2). RESULTADOS: Quanto aos quesitos avaliados, o G1 evidenciou 88,61% dos pacientes com queixa de dor pós-operatória com necessidade do uso de analgésicos e o G2, 28,85% (p<0,05). A média da graduação da dor através da escala analógica - de 0 a 10 - foi de 3,91±2,13 pontos no G1 e de 1,76±3,01 pontos no G2 (p<0,05). O período de recuperação variou de 26,63±13,3 dias para o G1 e 18,26±19,37 dias para o G2. O tempo médio até tornar-se assintomático foi 66,78±60,9 dias para G1 e 38,38±46,8 dias para G2. CONCLUSÃO: A RF propiciou menor dor pós-operatória e recuperação mais precoce quando comparada à SF.
